Patent DE-2114175-A1 (DE)
Title: Level stabilizer - separates two materials of differing density
Inventor: SPOTT GEORG DIPL-ING
IPC: B01D9/00
Filed: 1971-03-24
Abstract: A freely movable displacer is placed in a column such as a counter current crystallizer and is supported by one liquid phase. Covering up a sufficiently large area of the column section, the displacer is prevented from rising due to the viscosity of the upper denser phase material contg. solids.

Title: Extraction process using low-boiling solvents under press - and subsequent evaporation, esp. for concentrating organic trace substances
Inventor: GJAVOTCHANOFF STEFAN DIPL CHEM
IPC: G01N31/00
Filed: 1972-10-18
Abstract: The sample is extracted with a solvent which is gaseous under normal conditions, but which is liquefied under pressure. After separation the solvent is removed by reducing the pressure and allowing it to revert to gas. The solvent is pref. n-butane.

Title: Rescue equipment for prising open crushed car bodies - consists of jaws operated by hydraulic cylinder about centre linkages
Inventor: UNGER DIETRICH
IPC: B21D1/12
Filed: 1973-12-13
Abstract: The equipment consists of two prongs which can hinge about a pin mounted at the end of a piston rod of a hydraulic cylinder. The piston rod protrudes through a heavy gauge base plate on which the hydraulic cylinder is mounted. Linkages are mounted on points on the prongs which connect the prongs to the base plate. The points on the prongs to which the linkages are connected lie at either side of the point on the piston rod about which the two prongs can hinge. When the piston rod is extended, the hinge point of the two prongs will be pushed away from the base plate while the other points on the prongs will remain anchored to the base plate by the linkages. The ends of the prongs will therefore be forced apart by wedge action.

Title: Switching cct control for stabilised DC voltage regulator - multivibrator provides induced output in coupled windings of transformer
Inventor: POLLMEIER WERNER ING GRAD
IPC: H02M3/337
Filed: 1974-09-13
Abstract: A stabilised D.C. voltage regulator utilising a multi-vibrator stage is designed to avoid the susceptibility to damage of semi conductor devices due to transient spikes in the unstabilised supply voltage. The unstabilised supply voltage (G1) is coupled to a control transistor (T1) in series with an inductance (L1) and a transformer differential winding (W1, W2). The windings of the transformer (W1, W2) are controlled by a multi-vibrator formed by two transistors (T2, T3) and a control circuit (St). The coupled windings (W3, W4) have an induced voltage that is rectified by diodes (D3, D4) and capacitor (C2) smoothed to provide an output (A1, A2). The output is compared (VG) with a reference input (V1) and provides a control for the transistor (T1) to maintain the output at the required level.

Patent DE-2450348-A1 (DE)
Inventor: HASHIMOTO YUKIO
IPC: H03L1/02
Filed: 1974-10-23
Abstract: In addition to an oscillating circuit constructed as a clock pulse generator (91) and having a temperature frequency response as low as possible, the time-measuring instrument has a further oscillating circuit (92) which has a temperature frequency response deviating therefrom and preferably higher. A counter (98) counts the pulses of this further oscillating circuit and a temperature-dependent signal is formed by arranging for the counter results to be stored in a memory during a period which is essentially determined by a time counter (912) driven essentially by the clock pulse generator (91). Said signal is transmitted periodically to a frequency converter (91) whose output signal is used to correct the signal transmitted by the clock pulse generator to a reduction mechanism (911) which drives the time counter (912). At least some of the said circuit parts consist of CMOS integrated circuits. <IMAGE>
